lowspecgamer tweaks ingame settings to make them run better on older or crappier hardware. found this channel back when i used my laptop for gaming and wanted to actually play them at an acceptable framerate. i know most people here probably dont care because you might have an actually decent computer (even i do now) but i still find his videos informative
He also serves as a good proof of concepter. When asked why you would try to get a modern game to run on 10 year old hardware you can always just say... "Why not?" Imo he also shows how much of the bullshit hardware requirements can be and a lot of things should be configurable by the user without much headache but nooooo they don't want their game to be bale to look
that ugly.
The AT&T Tech Channel has some real gems. Here's probably the most popular one and it's how I found the rest.
On the Khernigan note, it's probably been mentioned but
Computerphile is a great tech channel for computer stuff. Some recurring great personalities and then notable computer wizards are regular guests.
They, along with
Numberphile, go into great detail on the Enigma Machine in some videos. Here's the Computerphile playlist for
The Enigma Machine and Turing,
I really like NumberPhile's videos on the enigma machine, they go into how it works to explain the combinations of codes. They explain in a separate video how to abuse the flaw to crack it. Not normally a technical channel, however.
Scott Manley, who started with Kerbal videos, has expanded into some realshit and covers some stuff in more detail than you'd normally get. Here's an interesting video that Americans may get a boner from. tl;dw US spy satellites are really, really, really, scary good and it's finally been verified by amateurs.
Here's a guy who spergs about security and is very easy to troll. He knows his stuff and he knows he knows his stuff, so has a bit of an ego that doesn't help him.
Rob Braxman. He may help out anyone who cares about digital privacy in general.
I love and loathe youtube. Remember folks, all these videos you care about should be downloaded.
